Figure 2From: A gait abnormality measure based on root mean square of trunk accelerationThe effect of preferred walking speed on RMS ratio (RMSR) in AP (a), ML (b) and V directions (c), and the effect of age on RMSR in AP (d), ML (e) and V directions (f). Each circle shows the RMSR of each healthy subject at his preferred walking speed. r s represents Spearman’s rank correlation coefficients.Back to article page
